get_vendor_id

Returns the vendor ID of this device, or null if this information couldn't be obtained.

This ID is retrieved from the device, and is thus constant for it.

This function, together with get_product_id, can be used to eg. compose Settings paths to store settings for this device.

 static GSettings *
 get_device_settings (GdkDevice *device)
 {
	 const gchar *vendor, *product;
	 GSettings *settings;
	 GdkDevice *device;
	 gchar *path;

	 vendor = gdk_device_get_vendor_id (device);
	 product = gdk_device_get_product_id (device);

	 path = g_strdup_printf ("/org/example/app/devices/%s:%s/", vendor, product);
	 settings = g_settings_new_with_path (DEVICE_SCHEMA, path);
	 g_free (path);

	 return settings;
 }

Parameters:

this	a slave Device

Returns:

the vendor ID, or null
